[QUOTE="Prostyle, post: 10664217, member: 99171"] yeah its exactly what tim and andy said. its the valve springs. The only reason im seeing the black exhaust smoke is because i have a leak in my upper intake and its escaping. You have to trust these guys. Its not there first 1 The car does fine until higher rpm. around 5.5-6k is where the smoke comes and it starts dropping. He did a pull on 19lbs and the car was making around 619 at around 4.8-5k rpm but then the black smoke came ha. most boost and it floats them earlier I dropped it down to 6 and it seems to be running just fine. Ill be ordering new springs and retainers soon! this is a task i do not want to do! such a pita [/QUOTE]
